To install module (before kernel 2.6.25) do:
# apt-get install mecurial
# hg clone http://linuxtv.org/hg/~tlorenz/v4l-dvb/
# make
# make install
# reboot
To bind device to right module, do:
# ls /sys/bus/usb/drivers/usbhid
My device number - is 1-10:1.2
# echo -n '1-10:1.2' > /sys/bus/usb/drivers/usbhid/unbind
# echo -n '1-10:1.2' > /sys/bus/usb/drivers/radio-si470x/bind
You can capture from tuner:
arecord -D plughw:1,0 -c 2 -r 96000 -f S16_LE -
Or sending to another sound card:
arecord -D plughw:1,0 -c 2 -r 96000 -f S16_LE - | aplay -D plughw:0,0 -c 2 -r 44100 -f S16_LE -
NOTE: If you want to hear clear sound, use 96Khz samplerate. Experimentally proved that sound on other samplerates is very distorted.
